[Sidenote: Contagious magic of teeth in Australia.] Among the Australian tribes it was a common practice to knock out one or more of a boy’s front teeth at those ceremonies of initiation to which every male member had to submit before he could enjoy the rights and privileges of a full-grown man.​[633] The reason of the practice is obscure; a conjecture on this subject has been hazarded above.​[634] All that concerns us here is the evidence of a belief that a sympathetic relation continued to exist between the lad and his teeth after the latter had been extracted from his gums. Thus among some of the tribes about the river Darling, in New South Wales, the extracted tooth was placed under the bark of a tree near a river or water-hole; if the bark grew over the tooth, or if the tooth fell into the water, all was well; but if it were exposed and the ants ran over it, the natives believed that the boy would suffer from a disease of the mouth.​[635] Among the Murring and other tribes of New South Wales the extracted tooth was at first taken care of by an old man, and then passed from one headman to another, until it had gone all round the community, when it came back to the lad’s father, and finally to the lad himself. But however it was thus conveyed from hand to hand, it might on no account be placed in a bag containing magical substances, for to do so would, they believed, put the owner of the tooth in great danger.​[636] The late Dr. Howitt once acted as custodian of the teeth which had been extracted from some novices at a ceremony of initiation, and the old men earnestly besought him not to carry them in a bag in which they knew that he had some quartz crystals. They declared that if he did so the magic of the crystals would pass into the teeth, and so injure the boys. Nearly a year after Dr. Howitt’s return from the ceremony he was visited by one of the principal men of the Murring tribe, who had travelled some two hundred and fifty miles from his home to fetch back the teeth. This man explained that he had been {p177} sent for them because one of the boys had fallen into ill health, and it was believed that the teeth had received some injury which had affected him. He was assured that the teeth had been kept in a box apart from any substances, like quartz crystals, which could influence them; and he returned home bearing the teeth with him carefully wrapt up and concealed.​[637] In the Dieri tribe of South Australia the teeth knocked out at initiation were bound up in emu feathers, and kept by the boy’s father or his next-of-kin until the mouth had healed, and even for long afterwards. Then the father, accompanied by a few old men, performed a ceremony for the purpose of taking all the supposed life out of the teeth. He made a low rumbling noise without uttering any words, blew two or three times with his mouth, and jerked the teeth through his hand to some little distance. After that he buried them about eighteen inches under ground.
